This Arduino Mega sketch uses direct port read and bit manipulations to sniff an i2c bus running at up to 100 kHz. The analysis of the i2c communication is displayed on the Serial monitor. Connect SDA ...

A comprehensive Arduino library for interfacing with the IPS-7100 Intelligent Particle Sensor over I2C communication. This repository is a fork of the original library from Piera Systems, modified for ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a helpful ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

The rig pictured above works as an Internet connected temperature sensor which sends [Zaion] an email with a graph of the change over time. This in itself is interesting, but one part in particular ...

The I2C Manual provides a broad overview of the various serial buses, why the I2C bus should be considered, technical detail of the I2C bus and how it works, previous limitations / solutions, ...
